Characters. — Face smooth. Palpus with second joint reaching beyond frons, rough-scaled 
(sometimes with strongly projecting hair-scales) above and beneath, third joint smooth, usually slightly 
fusiform, in cf moderate, in Q long. Tongue present. Antenna rather long, in c shortly bipectinate 
to little beyond one-half, distally nearly simple, in 9 nearly simple. Pectus extremely hairy, and usually 
with a very long pencil of hairs beneath base of forewing (Pl. 5). Femora strongly hairy. Hindtibia 
in cf with strong hair-pencil. and moderately long terminal process, both sexes with two unequal pairs 
of spurs. Abdomen not crested. Wings usually thinly scaled, the sexes often differing greatly in orna- 
mentation. Frenulum fully developed. Forewing with costa arched, apex moderate, termen subcrenulate 
or waved, oblique posteriorly, cell nearly one-half, DC incurved, strongly oblique posteriorly, SC! usually 
free, SC? variable in. position, but usually from but little before, very exceptionally even stalked 
to just after SC^, R'! separate, M! widely separate; hindwing with termen convex, typically crenulate, 
sometimes nearly smooth, but elbowed at R?, inner margin long, cell short (one-third to two-fifths), 
DC? oblique, DC? slightly incurved anteriorly, oblique or strongly oblique outwards through most of its 
course, C approximated or appressed to cell to one-half or less, then very rapidly diverging, SC? stalked, 
R? very characteristic, M! nearly always stalked, M? from near end of cell (Pl. 2, Fig. 1 4). c genitalia 
with uncus clubbed, spoon-shaped, slightly indented at the apex, socii shorter than uncus, gnathos 
terminating 1n a point, harpes with divided cucullus, clavus pointed, penis pestillate, broader at the 
tip, coremata present. 
Lanva. — Not fully described; provided with large flattened projections on both sides of the 
dorsum of each segment. That of jieroides feeds omn roses. (Turner, Proc. Limm. Soc. N. S. Wales, 
61:35: 0D03160521617)- 
Is at base a very natural genus, characterized by the combination of elongate, smooth third joint 
of palpus, long pectoral pencil of hair, strong tibial hair-pencil and process of c, long hindwing with 
short, obliquely-walled cell and stalking of radials, usually thin scaling and strong sexual dimorphism ; 
but will probably need purifying by the removal of some outliers such as moniliata, in which some of 
these characters are hardly developed. Turner sinks the genus to £ucyclodes, and. if some of the forms 
are really intermediate that may perhaps prove inevitable for taxonomic purposes; we are unfortunately 
unacquainted with the type of Eucyclodes, but as Turner describes it as having minute terminal joint to 
the palpus, and apparently different discocellulars. and as its facies is distinct and there is no sexual 
dimorphism, we have preferred, for the present, not to merge the better-known genus.
